 *    Retrieve the value for the supplied key from a PostScript font.
 *
 * @input:
 *    face ::
 *      PostScript face handle.
 *
 *    key ::
 *      An enumeration value representing the dictionary key to retrieve.
 *
 *    idx ::
 *      For array values, this specifies the index to be returned.
 *
 *    value ::
 *      A pointer to memory into which to write the value.
 *
 *    valen_len ::
 *      The size, in bytes, of the memory supplied for the value.
 *
 * @output:
 *    value ::
 *      The value matching the above key, if it exists.
 *
 * @return:
 *    The amount of memory (in bytes) required to hold the requested value
 *    (if it exists, -1 otherwise).
 *
 * @note:
 *    The values returned are not pointers into the internal structures of
 *    the face, but are 'fresh' copies, so that the memory containing them
 *    belongs to the calling application.  This also enforces the
 *    'read-only' nature of these values, i.e., this function cannot be
 *    used to manipulate the face.
 *
 *    `value` is a void pointer because the values returned can be of
 *    various types.
 *
 *    If either `value` is `NULL` or `value_len` is too small, just the
 *    required memory size for the requested entry is returned.
 *
 *    The `idx` parameter is used, not only to retrieve elements of, for
 *    example, the FontMatrix or FontBBox, but also to retrieve name keys
 *    from the CharStrings dictionary, and the charstrings themselves.  It
 *    is ignored for atomic values.
 *
 *    `PS_DICT_BLUE_SCALE` returns a value that is scaled up by 1000.  To
 *    get the value as in the font stream, you need to divide by 65536000.0
 *    (to remove the FT_Fixed scale, and the x1000 scale).
 *
 *    IMPORTANT: Only key/value pairs read by the FreeType interpreter can
 *    be retrieved.  So, for example, PostScript procedures such as NP, ND,
 *    and RD are not available.  Arbitrary keys are, obviously, not be
 *    available either.
 *
 *    If the font's format is not PostScript-based, this function returns
